The oral cavity is the first component of the digestive tract, which is delimited by the lips anteriorly and the oropharynx posteriorly. The oral cavity functions as a protective barrier and is an essential component for speech and swallowing, mastication, digestion, and taste sensation. In addiction the oral examination comprises a uniform and consistent inspection of the head and neck and an intraoral evaluation of the hard and soft tissues in conjunction with a thorough medical and dental history. The entire mouth should be inspected regardless of the child’s chief complaint and reasons for the visit. Good child’s history and careful examination are important to establish the correct diagnosis and provide appropriate treatment. How to approach an infant or a child for an oral exam, for example, allow child to sit in the parent’s lap during the physical examination with one of the parent’s hands holding the arms down and the other hand securing the child’s head against the parent’s chest; this facilitates cooperation and reduces the child’s anxiety. Use a game to help prepare the young child. Encourage the preschool child to use a tongue blade to look into a puppet’s mouth. Or place a mirror so that the child can look into the mouth while you do. The school-age child is usually cooperative and loves to show off missing or new teeth. Also, be discriminating in your use of the tongue blade. It may be necessary for a full view of oral structures, but it produces a strong gag reflex in the infant. As a nurse may avoid the tongue blade completely with a cooperative preschooler and school-age child. Try asking the young child to “Open your mouth as big as a lion,” “Can you stick out your WHOLE TONGUE?” and to move the tongue in different directions. To enlarge your view of the oropharynx, ask the child to stick out the tongue and “pant like a dog”. At some point, nurse will encounter an uncooperative young child who clenches the teeth and refuses to open the mouth. If all other efforts have failed, slide the tongue blade along the buccal mucosa and turn it between the back teeth. Push down to depress the tongue. This stimulates the gag reflex, and the child opens the mouth wide for a few seconds, so will have a brief look at the throat. Make the most of it. In conclusion, as a nurse should implement behaviors that show respect for child’s age, gender, cultural values and personal preferences, modify language and communicate style to be consistent with child’s needs, introduce yourself to the child and family and establish rapport. Use play techniques for infants and young children, and one of the most important is make eye contact if possible and address the child by name, being at the same eye level as the child can also be more reassuring, inspect teeth carefully, assess for eruption of teeth, and tooth loss and adult tooth formation and eruption consider the age and developmental stage of the child, and show respect, sensitivity and empathy are also important.
